Question

__________ electrons are the most important electrons to an atom.

Answer 1

Answer:

Valence electrons are the most important electrons to an atom.

Explanation:

They will determine many of the atoms traits since they are involved in bonding with other atoms.

Answer 2

Answer:

Valencia electrons are the most important electrons to an atom.

Explanation:

Valencia electrons are the electrons found in the last electronic layer, called valence orbitals, and these electrons are what determine the ability of the atom to form bonds. When an element joins another, it does so through its valence electrons.  These electrons participate in chemical reactions because these electrons are the electrons furthest from the nucleus of the atom.

And this electrons, in addition to determining the reactivity of the elements, allows to determine their location in the Periodic Table. All elements of the same group have the same number of valence electrons (This does not occur in transition metals). The valence electrons increase in number as one advances in a period.  Due to this, in a group the chemical properties are very similar.

Finally,Valencia electrons are the most important electrons to an atom.
